Es el estudio del comportamiento del agua y de otros líquidos, ya sea en reposo o en movimiento. Su estudio es importante ya que nos posibilita analizar las leyes que rigen el movimiento de los líquidos y las técnicas para el mejor aprovechamiento de las aguas.

Vázquez Santos, María Guadalupe
In this presentation we will talk about Magnetism its characteristics, properties and classification, since most of the magnets that are currently used are artificial, this is because they can be manufactured with a greater magnetic intensity than the natural ones, besides being more solid And ease to be molded according to the form that is needed. Not all metals can be magnetized and others, although they can acquire this property, they are easily released, either by external effects or spontaneously. Many magnets are made with nickel and aluminum or iron with chromium, cobalt, tungsten or molybdenum.

Guerrero Rodríguez, Windy Jacqueline
Generally the animal kingdom has been classified into two large groups: vertebrates and invertebrates, however this classification does not respond to an evolutionary criterion because not all invertebrates have a recent common predecessor.
At present, to classify the animals are used several criteria that try to deduce the evolutionary relations between the different groups. These criteria, which determine the degree of morphological complexity are:
Number of tissue layers in which cells are organized
The symmetry of the body and the arrangement of its parts
The presence or absence of body cavities (coelom) and the way they are formed
Developmental pattern from the fertilized ovum to the adult animal
Below is the classification and the most salient divisions of the animal kingdom and indicates the fundamental aspects that are used to group the different phylum (Aguirre & Ramirez, 2013).

Olvera Altamira, Christian
ISO is a topic that is used to refer to a set of established international standards for quality systems. These standards can be applied practically in any company, from product manufacturers, to service providers.
